It's not that bad, but an endgame with an obvious win (K+R vs K) seems pointless since there is an almost-certain winer. Now, something like a K+R+2P vs K+R+3P endgame would still have some chances for both players, so that has some potential. 😉

Umm, woudln't it be possible for people to simply copy the moves of the strongest player in the tournie? B+N Endings (as far as i'm aware) are pretty uniform in the move order. If David Tebb or someone like that entered an 1100 could just copy his moves surely?
